Geology of the Proterozoic Davenport Province, Central Australia

Australian Ocean Data Network hosts a geological dataset describing the Proterozoic Davenport province in central Australia. The description details rock formations, stratigraphy, geochemistry, and mineralisation, including recorded production of about 4500 tonnes of tungsten concentrates and 15 kg of gold. The dataset was last updated on 2026-06-05.

Use Cases

• Model mineral prospectivity based on described stratigraphy and known tungsten/gold mineralisation.
• Correlate geological units based on described geochemical signatures of felsic and mafic volcanics.
• Analyse tectonic history based on the described extensional ensialic setting and deformation episodes.
• Map subsurface geology using the described correlation with aeromagnetic data.

Strengths

• Description provides specific geological timelines, such as the 1870 Ma-old Warramunga Group and 1660 Ma-old granite intrusions.
• Includes quantified mineral production figures: about 4500 tonnes of tungsten concentrates and 15 kg of gold.
• Describes detailed stratigraphy, including a sequence at least 10 km thick with three subgroups and twenty formations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require parsing to extract structured data.
